Laser wakefield acceleration in the bubble regime for mid-IR laser drivers

ORAL

Abstract

We present work towards achieving laser wakefield acceleration in the bubble regime with a self-compressed mid-IR laser driver (20 mJ, 30 fs, λ=3.9µm). In order to access this regime, the laser is self-compressed through nonlinear spectral broadening and anomalous dispersion in CaF2 material. We will discuss the scaling of electron beam charge and quasi-monoenergetic beam energy with wavelength, supported by particle in cell simulations of the interaction.
